constexpr bool ends_with( std::basic_string_view<CharT,Traits> sv )     const noexcept;	(1)	(since C++20)
constexpr bool ends_with( CharT c ) const noexcept;	(2)	(since C++20)
constexpr bool ends_with( const CharT* s ) const;	(3)	(since C++20)

Checks if the string ends with the given suffix. The suffix may be one of the following:

1) a string view sv (which may be a result of implicit conversion from another std::basic_string).

2) a single character c.

3) a null-terminated character string s.

All three overloads effectively return std::basic_string_view<CharT, Traits>(data(), size()).ends_with(x), where x is the parameter.

Parameters

sv	-	a string view which may be a result of implicit conversion from another std::basic_string
c	-	a single character
s	-	a null-terminated character string

Return value

true if the string ends with the provided suffix, false otherwise.

Notes

Feature-test macro:

__cpp_lib_starts_ends_with

Example

Run this code

#include <iostream>
#include <string_view>
#include <string>
 
template <typename SuffixType>
void test_suffix_print(const std::string& str, SuffixType suffix)
{
    std::cout << '\'' << str << "' ends with '" << suffix << "': " <<
        str.ends_with(suffix) << '\n';
}
 
int main()
{
    std::boolalpha(std::cout);    
    auto helloWorld = std::string("hello world");
 
    test_suffix_print(helloWorld, std::string_view("world"));
 
    test_suffix_print(helloWorld, std::string_view("goodbye"));
 
    test_suffix_print(helloWorld, 'd');
 
    test_suffix_print(helloWorld, 'x');
}

Output:

'hello world' ends with 'world': true
'hello world' ends with 'goodbye': false
'hello world' ends with 'd': true
'hello world' ends with 'x': false
